Abstract

Treatment of silyl-substituted thioimidates with silver fluoride in the presence of a trapping agent produces dipolar cycloadducts formally derived from nitrile ylides. The ratio of cycloadducts obtained from the reaction of unsymmetrically substituted dipolarophiles with phenyl silyl thioimidate 8 wa8 found to be significantly different from that obtained from the photolysis of phenylazirine. We propose that the different product ratios encountered with ...
